This work deals with performance investigation of a linear actuator intended for Electronic Valve Control. Geometric, electric and magnetic parameters insuring valve maintain are carried out through a 3D finite element calculation. None polarized configuration, suffering from permanent supply of actuator coils, is upgraded to an enhanced hybrid topology arranged in an “A” way with nonmagnetic core-backs. Under extreme thermal conditions, it has been found that upgraded structure reduces energy consumption with an improvement of actuator’s capability of force generation.
